Scan Resolution not showing on PDFs

Greetings.

I recently added some Game Boy and SNES manuals, in PDF format. Each was scanned at 300 DPI and I entered that information when I uploaded them each, but there's just a question mark for their resolution when you look them up on the site.

Also, for some reason, Final Fight 2 is listed twice in the SNES manual section. Does anyone know why that is?

Thanks for a great site. =)
